Would like some advise about a few fans.

[Earzz]

Im busy with a PC-A05 build and im looking for some decent performing, silent fans.
Five or six fans in total, aircooling only and the used cooler is gonna be a TRUE (its gonna be used with current MB and CPU)
Im still considering push pull but space may be a issue.
I wasnt planning to use a fancontroller/adaptor because i want to keep the build as clean as possible.

Currently im on 3 S-Flex F fans and 3 elcheapo Revoltec fans, the Scythe fans are a bit noisy and the Revoltec fans just dont perform.

So here's my list of fans im looking at:

-Nanoxia DX12-900
-Nanoxia FX12-1250
-Scythe Gentle Typhoon 1150RPM
-Scythe S-Flex E

So your thoughts please about these fans.
If you got some other good fans that are available in the Netherlands i would be happy to hear it from you guys.

Cheers.
